Question

Which one of the following does not have $s{p}^2$ hybridised carbon?

• A. Acetone
• B. Acetic acid
• C. Acetonitrile
• D. Acetamide

Answer 1

Answer: (C)

[a] $\underset{s{p}^3}{C{H}_3}-\stackrel{O}{\underset{s{p}^2}{\stackrel{||}{C}}}-\underset{s{p}^3}{C{H}_3}$ [b] $\underset{s{p}^3}{C{H}_3}-\stackrel{O}{\underset{s{p}^2}{\stackrel{||}{C}}}-OH$ [c] $\underset{s{p}^3}{C{H}_3}-\underset{sp}{C}\equiv N$ [d] $\underset{s{p}^3}{C{H}_3}-\stackrel{O}{\underset{s{p}^2}{\stackrel{||}{C}}}-N{H}_2$
Acetonitrile does not contain $s{p}^2-$ hybridized carbon.
